Abstract:

Understanding the true extent of work accidents (WA) is essential for implementing effective prevention and worker health protection policies. This study aimed to estimate the magnitude of WA among employed and informal sector workers in Brazil. Using an extrapolation method based on the annual incidence of WA among individuals covered by the General Social Security System (RGPS), total WA cases were estimated for the Economically Active and Employed Population (PEAO) and the informal PEAO for the year 2019. The average incidence was 11.09 per 1,000 employment links, more pronounced among men, youth aged 14 to 24, and in the South region. An estimated 429,760 WA occurred among informal workers and 1,059,152 among the overall PEAO. Among informal male workers, the estimate was 308,200, and among informal workers aged 14 to 24, it was 94,581. The estimated underreporting rate was 44.6% (n=472,295). This study contributes to understanding the magnitude of WA in Brazil by addressing different characteristics and worker groups. Confirmation studies are needed to validate the obtained estimates.
